How to delete JPG files, but only if the matching RAW file exists?

Question

On debian terminal, I try to delete all .jpg of a folder and subfolder if .cr2 exist on the same folder.

Assumes they have the same name. 123.jpg 123.cr2

I know how to delete all .jpg with find command.

find {PATH} -type f -name '*.jpg' -delete

but how can I add a condition (if .cr2 exist)

I found this 10y topics but it's for windows and python

You can try something like:

shopt -s globstar
for i in /path/**.jpg
do
RAW=${i%.jpg}.cr2
if [ -f "$RAW" ]
then rm "$i"
fi
done

If you are fan of oneliners you can convert the script to something like:

shopt -s globstar; for i in /path/**.jpg; do [ -f "${i%.jpg}.cr2" ] && rm "$i"; done
